Letters Patent No. 90,281 dated May 18,1869.

' mPROVED MACHINE I OR PUNCHING- LEATHER STRAPS FOR FLY-NETS.

The Schedule referred to in these Letters Patant'and making p 111: ofthe same.

To all whom 'it may concern:

Be it known that I, JOHN MATHEIS, of Ottawa, in the county of La Salle,in the State of Illinois, have invented a new and useful Improvement ina Machine for Punching Leather Straps for Fly-Nets; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figures 1 and 2 are vertical plans Figure 3, a section through a b, fig.2;

Figure 4, a horizontal plan;

Figure 5. a w of the under side of the machine; and

Figures 6 and 7- are detached pieces.

My invention consists in an improved feeding-device, whereby themachine, as heretofore built by me, and secured by a patent of theUnited States, is reduced in bulk and weight and cheapened in itsconstruction.

It becomes thus more especially adapted to the purpose of smallmanufacturers whose limited trade does not permit them the outlay of theheavier and more expensive machine.

- My invention also consists in an improved pressurefoot to hold downthe work on to the bed-plate.

I construct, of cast-iron, a bedsplate, A, having four legs, and towhich are bolted the two frame-pieces B B These framepieces are alsoconnected by the bar 0, through which passes the punching-bar D, drivenby the crank on the shaftE.

On one end of the shaft E is the fly-wheel F, with a handle ,G.

On the other end of the same shaft is an adjustable crank, H, to whichis attached the pitman I.

This pitman, I, is attached to one end of the lever J, having itsfulcrum at K, while the other end projects through and under thebed-plate A, and is there connected with the pitinan L, thuscommunicating motion to the feed-bar M, fig. 6. j v

This feed-bar, M, has, besides this longitudinal motion, also a verticalmotion, which it receives from the rod N, having at its lower end across-head, O, with a nut, while the upper end runs on the eccentric P,which is so set on the shaft E'that the rod N and the feedbar Mareraised up at the end of the stroke.

The feed-bar M then engages the nipple c of the gauge-bar Q, fig. 7, andslides forward thereon, being held up against the work until theenlarged place (I, on the feed-bar M, fig. 6, meets the nipple c, fig.7,

when said feed-bar falls down and ceases to feed,

although it may not then have arrived at the end of the stroke. As thegauge-bar Q is movable in slots 0 e, fig. 7, and'can be fastened by theset-screw f, it will be seen that by moving said bar, Q, in or ont,thelength of the feed (that is, the distance betweenthe holes to bepunched) can be regulated at will, and for this purpose-there is on it aseries of marks, 9 g g,- fig. 7, by which the workman is governed inadjusting the machine.

A pressure-foot, in some respects similar to those used forsewing-machines, is adapted to the bed-plate A. It consists of the plateR, the rod S, and the lever T, which lever is so shaped, that by raisingit up in a vertical position, its short end rests on the support U,thereby holding up the plate R off from the work.

When the lever '1. is turned'down, the spring V, pressing on the plateR, presses down the same on to the work.

Gauges, W W, sliding in ways, and fastened by set I screws, Y Y, areadapted on each side.

I claim as my improvement, and desire to secure by Letters Patent thefollowing parts, disclaiining all other 'parts- 1. The feeding-device,composed of the combination of the adjustable crank H,-the pitman I, thelever J, the pitman L, the feed-bar M, the rod-N, with eccen-' tricP,and the gauge-bar Q, the same only when
